Student or Learner
i'm a croatian student of English, and recently I had my English language exam, and I was required to use lest in a complex sentence to show that I know how to use it.
anyways, I wrote a bare infinitive subordinate clause, and my teacher corrected me and said that I should have used "should" instead of "bare infinitive".
I'm not sure, but I think she was wrong. could someone help me solve this problem?
thank you very much
It is very hard to comment without seeing the sentence you wrote, but 'lest' does not need a 'should'. In fact it is normally used without a 'should'.
Probably the most common sight of 'lest' is on WW1 war memorials, where it says "Lest we forget" - without a 'should'.
